[0002] Flexible ultra-thin glass is a new type of ultra-thin glass with a thickness of ≤0.1mm, extremely light weight and flexibility. It does not require heat processing and can be bent and rolled arbitrarily under external force. It not only has the high hardness, high transmittance and stable mechanical and chemical properties of ordinary glass, but also has excellent chemical resistance, low thermal expansion and high thermal stability. It can effectively block water vapor and oxygen, and has great advantages in the preparation of flexible substrates and cover materials. It is widely used in display panels, flexible display substrates, smart surfaces, OLED lighting and flexible solar cells.

[0003] When manufacturing flexible ultra-thin glass, it is necessary to perform strength tests on the edges of the flexible ultra-thin glass. During the test, the flexible ultra-thin glass needs to be fixed on the inspection table. Because the flexible ultra-thin glass needs to be subjected to a large impact force during the test, sufficient fixing force needs to be applied when fixing the flexible ultra-thin glass. However, a large force may cause the flexible ultra-thin glass to break. In addition, during the test, the flexible ultra-thin glass with different functions needs to be tested with different forces and directions. Therefore, a device that can adjust the test force and direction is needed.

[0004] The utility model designs a testing device for edge strength of flexible glass to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A testing device for edge strength of flexible glass comprises legs, an inspection table, a fixing assembly and an impact assembly, wherein the inspection table is fixed by a plurality of evenly distributed legs; four fixing assemblies are evenly mounted on the inspection table, and the flexible ultra-thin glass is mounted on the four fixing assemblies; and the impact assembly is mounted on the inspection table.

[0007] An arc-shaped slide groove is provided on the inspection table.

[0008] The impact assembly includes a motor, a gear, an arc-shaped slider, an impact block, a pull rod, a second spring, an adjustment assembly, and a mounting block, wherein the motor is installed on the lower side of the inspection table, a gear is fixedly installed on the output shaft of the motor, the outer arc surface of the arc-shaped slider has teeth, the arc-shaped slider is slidably installed in the arc-shaped slide groove, and the teeth on the arc-shaped slider are meshed with the gear; a mounting block is fixedly installed on the arc-shaped slider, a pull rod is slidably installed on the mounting block, and an impact block is fixedly installed on one end of the pull rod; a second spring is installed between the other end of the pull rod and the mounting block, and the second spring is a tension spring; two adjustment assemblies that can adjust the length of the working area of ​​the second spring are symmetrically installed on the mounting block.

[0010] As a preferred solution, a first elastic pad is fixedly mounted on the inner wall surface of the lower end of the fixed clamping plate.

[0011] As a preferred solution, a second elastic pad is fixedly mounted on the bottom of the clamping plate.

[0012] As a preferred solution, the adjustment assembly includes a fixed plate, a mounting piece, a guide slide bar, an insert plate, and a tightening bolt, wherein the fixed plate is fixedly mounted on the mounting block, a guide slide bar is fixedly mounted on the upper side of the fixed plate, a mounting piece is slidably mounted on the guide slide bar, a tightening bolt is installed between the mounting piece and the fixed plate; an insert plate is swingably mounted on the mounting piece; and the insert plate cooperates with a second spring.

[0013] Compared with the existing technology, the advantages of the utility model are:

[0014] 1.

In order to achieve this effect, the present invention arranges two adjustment components on the mounting block. When adjusting the adjustment components, the mounting member is driven to slide on the guide slide rod. After the position of the mounting member is determined, the mounting member is fixed to the fixed plate by tightening the bolts, and then the plug plate installed on the mounting member is swung so that the plug plate is inserted into the gap of the second spring, so that the second spring is divided into two parts by the plug plate. In this case, when the pull rod is pulled, the second spring close to one side of the mounting block will not be stretched, while the spring on the other side will be stretched. When the pull rod is released, only the stretched second spring will apply driving force to the impact block; in this way, compared with the second spring being stretched as a whole, more impact tests with different impact forces can be obtained, thereby improving the impact test effect.

[0029] like Figure 2 , 5 As shown, the impact assembly 5 includes a motor 6, a gear 7, an arc-shaped slider 8, an impact block 18, a pull rod 19, a second spring 20, an adjustment assembly 21, and a mounting block 22, wherein the motor 6 is mounted on the lower side of the inspection table 2, the gear 7 is fixedly mounted on the output shaft of the motor 6, the outer arc surface of the arc-shaped slider 8 has teeth, the arc-shaped slider 8 is slidably mounted in the arc-shaped slide groove 23, and the teeth on the arc-shaped slider 8 are meshed with the gear 7; as shown Figure 5 As shown, a mounting block 22 is fixedly installed on the arc-shaped slider 8, a pull rod 19 is slidably installed on the mounting block 22, and an impact block 18 is fixedly installed on one end of the pull rod 19; a second spring 20 is installed between the other end of the pull rod 19 and the mounting block 22, and the second spring 20 is a tension spring; two adjustment components 21 are symmetrically installed on the mounting block 22.

[0030] The motor 6 is controlled to work, and the motor 6 can drive the gear 7 to rotate. The rotation of the gear 7 drives the arc-shaped slider 8 to slide along the arc-shaped slide groove 23. The sliding of the arc-shaped slider 8 drives the mounting block 22 to slide.

The multi-directional impact test of the flexible ultra-thin glass 3 is realized, and the flexibility of the test is improved.

[0031] During the test, the pull rod 19 is pulled to stretch the second spring 20; then the pull rod 19 is released so that the pull rod 19 slides toward the side of the flexible ultra-thin glass 3 under the action of the second spring 20, and the sliding of the pull rod 19 drives the impact block 18 to slide, so that the impact block 18 hits the flexible ultra-thin glass 3, and an impact test is performed on the edge of the flexible ultra-thin glass 3; the magnitude of the impact force can be determined according to the stretching amplitude of the second spring 20.

[0033] In order to more flexibly test the parameter changes of the edge of the flexible ultra-thin glass 3 at different impact forces, the more impact force changes that the impact block 18 can provide, the better the test effect. In order to achieve this effect, the present invention sets two adjustment components 21 on the mounting block 22. When adjusting the adjustment component 21, the mounting member 27 is driven to slide on the guide slide bar 28. After the position of the mounting member 27 is determined, the mounting member 27 is fixed to the fixed plate 26 by tightening the bolt 30, and then the plug plate 29 installed on the mounting member 27 is swung so that the plug plate 29 is inserted into the gap of the second spring 20, so that the second spring 20 is divided into two parts by the plug plate 29.
